Trailer brake warning

- Kingsville, MO, USA

The rear window of my 2017 Chevy Silverado exploded. I had the rear defrosters on, and they malfunctioned. I thought I smelled something hot before this happened. I am surprised this didn't cause a fire. I have researched this issue, and it appears to be an ongoing problem with the 2014 - 2019 Silverado and Sierra trucks. In fact, Canada has a recall on this issue, but the U.S. does not. Why is that?

After starting the vehicle. I heard a hissing noise coming from the rear of the cabin. I looked in the rear view mirror and saw a large amount smoke rising from the box where the rear defroster power connects to the window. I immediately shut the vehicle off, got out and walked around the passenger side of the vehicle. As I approached the passenger rear door, the rear passenger window exploded with a Loud pop, shooting glass across the bed of the truck. I know there is currently a recall for this issue in Canada.

When driving all gauges go to zero, truck doesn-??t illuminate which gear it-??s in, warning lights come on (service 4WD, service stabilitrak, service traction control, reduced power steering, service traction control, service trailer brake system ). When NOT driving if these issues show on the dash when parked and the car doesn-??t illuminate which gear it-??s in, it does not crank over, does not start, there is no clicking noise either like if it was a bad starter. All the dash lights, gauges, radio goes black as if I turn the vehicle off instead of on. This has been happening since around 2020-2021 in Colorado. It was in a shop for over a month with no resolution. In Idaho in 2022-2024 in a shop for a month with no resolution, and now CA in 2025. No mechanic shop can figure out what is wrong, no -??certified GM-?? shop or -??certified GM engineer/technician can tell me what-??s wrong. I have had the following replaced already and still having issues. Body Control Module (BCM), the Transfer Case control Module (TCCM), and the Brake Control Module (BCM).

Issue is based off of this service bulletin, but GM has failed to call a recall on this for coverage. I was driving my daughter to softball practice. Every few minutes there would be a "stabilitrak" message showing on the driving information area. Then in slower speeds my dashboard screen would blank out and then go back to CarPlay. Then once I approached a parking lot at slower speeds my vehicle lost total power and shut down. Then had to switching the gear to park, then turn off the ignition key, then wait a few seconds and turn the key on to start the truck. It started as normal and was able to park in the parking space. Very scary and this is a very serious issue, I could have been in an accident with my daughter. This has to be addressed, I can't be the only one having this issue.

Electronics for hands free stopped working. This part was already replaced once. When backing up, the whole truck shut down. I restarted, it said to roll drivers side window down and up. Truck started up again. Few days later... returning from trip, lost power, windshield wipers came on, electronics in truck started blinking. Pulled over, rolled driver's side window up and down. started back on road. This has happened numerous times. Whenever I gave it extra gas, asking for power to pass, same thing mentioned above happened. Very stressful! Next day, hit a hole, truck totally shut down again. Husband was able to safely coast off road, however, if he had been pulling out at a major intersection, this could have been bad. Warning light that comes with shutdown says "stabltrack issue". I have not seen our dealer service department yet, but plan to very soon. VERY unsafe... and I love this truck!!!!

The AFM system is a faulty system that starved my lifters of oil and they ended up collapsing causing a flat spot on my cam. The engine code would come up as a misfire but the code is caused by the flat spot created on the cam by the lifter it's a faulty system that cost me $7,000. My 8spd transmission also has a hard shift from 1st to 2nd pushing the vehicle forward and jerking it when it shifts. The dealer and GM said this was natural with this type of transmissions which we now know is a lie.

At night when in reverse, the dash camera does not dim as the rest of the dash does. The screen is far too bright inside the passenger compartment and you cannot safely maneuver the vehicle. There is no manual adjustments available.

I was parked at a gas pump, just got done fueling, hung hose up. I quickly ran into the gas station to grab a drink and as temps are 0?F, I remote started my vehicle from check out counter. When I returned to my vehicle the cab was filling with smoke. I sprung into action and quickly but safely drove away from gas pump with very little visibility, due to smoke, I assessed what was going on. Upon further investigating where the fire was coming from, I Could see the smoke was billowing from my rear window. As I Went to check on window heater that turns on automatically with remote start, the windows left panel exploded in my face from the outside of truck. Minor glass cuts, no major injuries. No insurance claims filed, no emergency services called as after I extinguished fire and turned off vehicle smoke seemed to have dissipated enough to safely get home 4 minutes away. As preventive messures I pulled the fuse to the rear window defroster so it is no longer getting power. This is seriously a safety hazard and thankfully I was able to pull away from gas pump. My truck, not so lucky. After looking into the issue when I got home, the US has NOT filed a recall on rear window defrosters for truck years 2014-2019. Canada DOES have a recall for this issue. As it has happened to me in the US in a very scary manor this needs to be addressed. I can-??t imagine what would have happened if I was driving with kids in the rear seat. This needs to be taken care of and not at owners expense. Americans buy new vehicles to feel safe and secure. After owning my vehicle I have second thoughts about owning new, especially if a fire happens due to electronics built into the vehicle. I pray we can have this issue resolved to save all the innocent GM truck owners with families and friends who would also like to feel safe in their trucks. With temps this low in New England, I would like to be able to use my window defroster and have safer fields of view in icy/snowy conditions.

2 times total electrical and engine failure while driving.

As I was driving I received a call while my phone was plugged in to the USB charging port and as I answered the call all the gauges on my dash, as well as the radio and all my warning lights shut off and turned back on and calibrated as if I first started the vehicle and reset. Then the radio and things wouldn't work. I had to pull over shut off the truck and restart it. This has happened 2 times already in less than as year I contacted the dealer and they really don't seem to care and keep putting me off or telling me they will call me which never happens. As of writing this still not fixed.

This is a complaint in regards to the trailer breaking system in my certified pre-owned 2017 Chevy Silverado that I purchased in April of this year, 2024. I purchased this truck in particular for its high ratings in safety and towing capabilities. (April- May 2024) While towing a 22ft trailer from Virginia to Washington state, there were several moments where the -??service trailer braking system-?? alert would appear on the dash. Driving on the interstate for days on end is twice as stressful when you have to wonder if your trailer brakes are reliable. If the trailer brakes were to suddenly stop working it would be dangerous for me and my passengers, as well as those around me on the road. (Sept- Oct 2024) We aren-??t towing a trailer anymore, but the -??service trailer braking system-?? light has been going off every couple minutes.

I am filing a complaint regarding an electrical fire in the junction box of my 2017 Chevy Silverado 1500. The issue began when the front passenger side marker light would not turn off. I disconnected the battery overnight to troubleshoot the problem. However, when I reconnected the battery the next morning, an electrical fire occurred in the fuse junction box under the hood. At the same time, the engine unexpectedly attempted to turn over and start on its own. I immediately disconnected the battery again to stop the fire. Upon inspection, I found that several wires, plugs, and the top half of the junction box had sustained significant damage.

Engine shuts down on its own causing steering wheel to jerk and almost locks preventing control. Has been doing this for three weeks and is now getting much worse. Seems to do when making slow speed sharp turn. Almost hit another car in intersection yesterday due to steering control loss. I have seen numerous mentions of this on the internet but seems GM does not have a fix. The truck is now dangerous to drive as it can completely shut down in the middle of an intersection.

My vehicle radio goes crazy, but oddly the speedometer goes away as well. I was able to get it back by turning radio off completely, but this should be a recall issue. Please help.
